Peter; just clicking on the link should work. I think making it private means that it can't be played by someone who goes to my soundcloud page. The direct link posted above is required. If it's not working, try a different browser.
Greg; I think some of that "underwater"-ness is that I have too much low-mid, which I think is partly my chord voicing and partly my tone settings. Part of the learning process; I'll have to work on that. Plus some of those mis-fingerings, and still learning to use the volume pedal, are setting off delay artifacts, which I guess adds a sonar element to the underwater impression.
Thanks for the complements everyone.
